@bogle: "I have the use of a laptop (Dell Latitude D505) that I plan to use to 
log data via at the serial port.  The logger runs as a service, writing 
to a file.  My question relates to the power saving settings.  Do I need 
to set it in the mode where (a) the hard drive never turns off and (b) 
it never goes into stand-by?  I'm thinking about this because I'll need 
it to run for about 1 1/2 to 2 hours on battery.
Thanks
Gib"
    @jameswest: "what sort of data
a stream or a burst?
I would leave the HD on  if a stream as starting and stopping would reduce 
the life faster
turn off the screen and you should manage 2 hours depending on how old the 
battery is
